STRUCTURAL UNIT Filed May 21, 1928 IN VEN TOR A TTORNEYS Patented June17, 1930 UNITED. STATES PATENT OFFICE DEWEY H. BITNEY, F ALBION,MICHIGAN, ASSIGNOR TO UNION STEEL PRODUCTS COMPANY, OF ALBION, MICHIGANSTRUCTURAL UNIT Application filed May 21, 1928. Serial No. 279,225.

The main object of this invention is to provide a structural unit foruse in attaching floor sleepers, furring or the like to concretefoundations and walls.

A further object is to provide a structural unit of the characterindicated in which a plurality of attaching members may besimultaneously set or placed in proper spaced relation.

A still further object is to provide a structure having these advantagesin which the clips or anchoring elements are not likely to be broken offalthough subject to severe usage prior to their attachment to the partto be anchored.

Ob'ects relating to details and economies of construction and operationof my invention will appear from the detailed description to follow. Theinvention is defined and pointed out in the claim.

A structure which is a preferred embodiment of my invention isillustrated in the accompanying drawing, forming a part of thisapplication, in which: i

Fig. 1 is a fragmentary perspective view of a concrete wall orfoundation having a series of my improved structural units in positiontherein and attached to the furring or sleepers.

Fig. 2 is a detail section.

Fig. 3 is a fragmentary side elevation of one of my improved structuralunits.

Fig. 4-. is a detail section on a line corresponding to line 4- of Fig.3.

In the drawing similar reference characters Y refer to similar partsthroughout the several views.

Referring to the drawing, 1 represents a concrete foundation or wall and2 floor sleepers or furring pieces.

In Fig. 1,1 show portions of a plurality of my improved structuralunits, each unit comprising a longitudinal rod 3 of substantial lengthand a plurality of combined anchoring and attaching membersdesignatedgenerally by the numeral 4.

These attaching members are formed of bendable wire and are of a generalU-shape one arm 5 of each member being welded to the longitudinal rod intransverse relation adapted to be imbedded in the concrete as shown inFig. 2, the same being pushed into the concrete while it is in a plasticcondition. When it is desired to attach the parts 2, the attachingmembers 7 are bent to an upright position, as shownin Fig. 2.

Thus arranged, the members are not likely to be broken from the rodeither when the attaching members are straightened up to operativeposition or by being stepped on or having a wheel pass over the same orsome such fall thereon during the building operations which are usuallycarried on after the floor foundation has been laid and prior to thelaying of the floor.

The U-shape of the anchoring legs also serves to provide very efiicientanchors.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is: 7

An anchoring unit for concrete structures comprising a longitudinal rodof substantial length and a plurality of U-shaped combined anchoring andattaching members having one arm longer than the other and angled, saidmembers being disposed transversely of the longitudinal rod and theirshorter arms welded thereto, the angled arms being adapted to be bent toupright positions for attachment to the members to be secured, the bightportions of said members constituting anchoring members adapted to beimbedded in a concrete body.
